When it comes to roofing, homeowners today want more than just protection—they want materials that are durable, affordable, and low-maintenance. That’s why composition roofing has become one of the most popular choices across the U.S. But what exactly is a composition roof, and how does it compare to other materials?
In this article, we’ll explain what composition shingles are made of, the different types available, and the real-world advantages they offer for homeowners seeking long-term value without breaking the bank.
What Is Composition Roofing?
Composition roofing—also called composite roof shingles—refers to asphalt-based shingles made from a blend of materials such as fiberglass, mineral granules, and asphalt. This combination makes the shingles flexible, weather-resistant, and available in a variety of styles to suit any architectural design. They’re especially popular for residential homes due to their balance of cost, appearance, and performance.
Types of Composition Shingles
There’s no one-size-fits-all approach when it comes to composite shingles. Here are the most common categories you’ll find on the market today:
3-Tab Shingles
These are flat, uniform shingles made with a single asphalt layer and three tabs per strip. They’re lightweight and budget-friendly but tend to have shorter lifespans—typically around 20–25 years.
Architectural (Dimensional) Shingles
These thicker, multi-layered shingles mimic the appearance of wood shake or slate. They offer greater durability and visual depth and are often backed by warranties of 30 years or more.
Luxury or Premium Shingles
Designed to replicate high-end materials like slate or tile, luxury shingles offer top-tier protection and aesthetics. They’re heavier and more expensive but ideal for homeowners who want upscale curb appeal without the cost of real stone or clay.
